Biography

I am an incoming MSc student in the Department of Computer Science and Engineering at The Chinese University of Hong Kong (starting Fall 2026). I received my bachelor's degree from Harbin Institute of Technology, Shenzhen in 2026, where I was advised by Prof. Shuo Yang.

Research Interests

My research interests lie in multi-modal content understanding and generation, which include:

• Vision-language alignment in Multi-modal Large Language Models (MLLM)
• Reinforcement Learning from Human Feedback (RLHF) in MLLM
• Unified multi-modal understanding and generation with mutual enhancement

🔍 I am currently seeking full-time positions starting from Fall 2027 related to Multi-modal Large Language Models (MLLM). Please feel free to contact me if you have any opportunities!
